±16.5kV ESD Protected, 1.8V, Micro Power, +125°C, 1/8 Unit Load,
RS-485/RS-422 Differential Receivers
The ISL32610E, ISL32611E, ISL32612E are ±16.5kV
IEC61000 ESD protected, fractional unit load (UL), 1.8V
powered, single differential receivers (Rx) for balanced data
communication using the RS-485 and RS-422 standards. With
their 85µA supply currents, the receivers are optimized for low
power applications, and deliver the lowest supply currents of
any available single Rx IC (see Figure 1).
Features
To improve performance in low data rate applications with
slow signal transitions, these Rx feature symmetrical switching
points (±200mV) and increased hysteresis. The symmetrical
switching points eliminate the duty cycle distortion introduced
by full-failsafe type receivers (see Figure 2), while the larger
hysteresis increases noise immunity.
• Symmetrical Switching Thresholds for Less Duty Cycle
Distortion (see Figure 2)
• Wide Supply Voltage Range . . . . . . . . . . . . . . . . . 1.8V to 3.6V
• Ultra Low Quiescent Supply Current . . . . 110µA (maximum)
• IEC61000 ESD Protection on RS-485 Bus Pins . . . . ±16.5kV
- Class 3 ESD Level on all Other Pins. . . . . . . . . . >8kV HBM
• Larger Hysteresis for Improved Noise Immunity . . . . . 70mV
• Data Rates up to 256kbps (1.8V) or 500kbps (3.3V)
• 1/8 Unit Load Allows up to 256 Devices on the RS-485 Bus
• Specified for +125°C Operation
The receivers present a 1/8 unit load to the data bus, which
allows up to 256 devices on the network for large node count
systems (for example, process automation, remote meter
reading systems). The ISL32611E/ISL32612E Rx output is
tri-statable using the RE/RE input.
• Three-State Rx Output Available
• 5V tolerant logic inputs
• Pb-Free (RoHS Compliant)
Applications
The receiver inputs feature a failsafe-if-open design, which
ensures a logic high Rx output if Rx inputs are floating. Data
rates up to 256kbps are achievable with this device at
VCC = 1.8V.
• Industrial/Process Control Networks, Factory Automation
• High Node Count Networks
• Space Constrained Systems
See Table 1 for a summary of each device’s features. For a
companion 1.8V differential transmitter in a SOT-23 package,
reference the ISL32613E datasheet.

NOTES:
1. See TB347 for details about reel specifications.
2. These Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte tin plate
plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Pb-free products are
MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), see ISL32610E, ISL32611E, ISL32612E.device pages. For more information about MSL, see TB363.
4. The part marking is located on the bottom of the part.

All Pins
NOTES:
8. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
9. Currents into device pins are positive; currents out of device pins are negative. Voltages are referenced to ground unless otherwise specified.
10. The ISL32611E enters SHDN whenever RE switches high, and the ISL32612E enters SHDN whenever RE switches low.
11. Devices meeting these limits are denoted as 1/8 unit load (1/8 UL)” transceivers. The RS-485 standard allows up to 32 unit loads on the bus, so there
can be 256 1/8 UL devices on a bus.
12. Not applicable to the ISL32610E.

Application Information
Features
The ISL3261xE devices use a differential input receiver for
maximum noise immunity and common-mode rejection. Input
sensitivity is ±200mV, as required by the RS-422 and RS-485
standards. The symmetrical ±200mV switching thresholds of the
receivers deliver less duty cycle distortion than similar receivers
with a full-failsafe design (for example, skewed low/high input
thresholds, (such as -200mV/-20mV), which increase the high bit
width). This distortion is especially noticeable when the Rx is
driven by slow input transitions (see Figure 2).
The symmetrical input thresholds also allow more room for
increased input hysteresis, thereby increasing the Rx noise
immunity. The 70mV hysteresis of this Rx is twice the amount
specified for most full-failsafe devices.
Receiver input resistance of 96kΩ surpasses the RS-422
specification of 4kΩ, and it is eight times the RS-485 Unit Load
(UL)” requirement of 12kΩ minimum. Therefore, the products are
known as one-eighth UL” receivers, and there can be up to 256 of
the devices on a network while still complying with the RS-485
loading specification.
Receiver inputs function with common-mode voltages (CMV) of
±2V with VCC = 1.8V, and with CMVs of -7V to +12V for
VCC ≥ 2.7V.
All the receivers include a failsafe-if-open” function that
guarantees a high level receiver output if the receiver inputs are
unconnected (floating). As mentioned previously, the full-failsafe
function is not implemented to deliver output duty cycles that
better match the input.
Receivers support data rates up to 256kbps (VCC = 1.8V) or
500kbps (VCC ≥ 3V), and receiver outputs of the ISL32611E and
ISL32612E are three-statable using the active low RE or active
high RE input.
Data Rate Recommendations
When coupled with the ISL32613E or ISL32614E 1.8V
transmitter ICs, the receivers are useful for networks up to 4000’
(1220m) long, or for data rates up to 500kbps. For 4000’
distances with VCC = 1.8V, the ISL32613E can be used with any
of these receivers at data rates ≤ 50kbps. With VCC = 3.3V, any
transmitter/receiver combination operates over 4000’ at rates
up to 128kbps. Shorter networks allow data rates up to 500kbps,
as shown in Figures 11, 12, 13 and 14.
Low Power Shutdown Mode (ISL32611E and
ISL32612E)
The devices use a fraction of the power required by most
differential receivers (see Figure 1), but they also include a
shutdown feature that reduces the already low quiescent ICC
even further. The ISL32611E and ISL32612E enter shutdown
whenever the receiver is disabled (RE = GND or RE = VCC).
ESD Protection
All pins on the devices include class 3 (>6kV) Human Body Model
(HBM) ESD protection structures, but the bus pins (Rx inputs)
incorporate advanced structures allowing them to survive ESD
events in excess of ±16.5kV HBM and ±16.5kV IEC61000. The
bus pins are particularly vulnerable to ESD damage because they
typically connect to an exposed port on the exterior of the
finished product. Simply touching the port pins, or connecting a
cable, can cause an ESD event that might destroy unprotected
ICs. The new ESD structures protect the device whether or not it
is powered up, and without degrading the common-mode range.
This built-in ESD protection eliminates the need for board-level
protection structures (e.g., transient suppression diodes), and the
associated, undesirable capacitive load they present.
IEC61000-4-2 Testing
The IEC61000 test method applies to finished equipment, rather
than to an individual IC. Therefore, the pins most likely to suffer
an ESD event are those that are exposed to the outside world (the
bus pins in this case), and the IC is tested in its typical application
configuration (power applied) rather than testing each pin-to-pin
combination. The smaller value current limiting resistor coupled
with the larger charge storage capacitor yields a test that is much
more severe than the HBM test. The extra ESD protection built
into this device’s bus pins allows the design of equipment
meeting level 4 criteria without the need for additional
board-level protection on the I/O port.
AIR-GAP DISCHARGE TEST METHOD
For the air-gap discharge test method, a charged probe tip moves
toward the IC pin until the voltage arcs to it. The current
waveform delivered to the IC pin depends on approach speed,
humidity, temperature, etc., so it is difficult to obtain repeatable
results. The A and B pins withstand ±16.5kV air-gap discharges.
CONTACT DISCHARGE TEST METHOD
During the contact discharge test, the probe contacts the tested
pin before the probe tip is energized, thereby eliminating the
variables associated with the air-gap discharge. The result is a
more repeatable and predictable test, but equipment limits
prevent testing devices at voltages higher than ±9kV. The
ISL32610E, ISL32611E, and ISL32612E survive ±9kV contact
discharges on the bus pins.
Network termination resistors are only recommended for
networks operating at VCC ≥ 2.7V, and using termination
resistors may allow for higher data rates.
